IMPROVEMENTIN ANNULAR LEATHER WASHERS.

Specification forming part of Lrttezs Patent No. 146,062, dattd December30,1573; application ihd October 17, 1873.

To all whom it may concern:

Be it known that I, PIERRE L. GIBBs, of

^ Chicago, in the county of Cook and State of Illinois, have invented anImproved Annular Leather Washer, of which the following is aspecification Figure 1 is a face view'of my improved leather washer;Fig. 2, an edge View thereof, and Fig. 3 a face view of the leatherstrapfrom which the washer is formed.

Similar letters of reference indicate corref sponding parts in all thegures.

The object of this invention is to economize material in theconstruction of leather wash ers Vfor journals for car-axles and otherpurposes.

`Vashers for that purpose are usually cut out whole from pieces ofleather of the requisite size, and a large percentage of leather is,therefore, necessarily wasted.

My improved washer is made out of a leather strap which is rolled orbent while Wet, and brought to the requisite form, and then riveted p orotherwise joined at the ends.

In the accompanying drawing, the letter A represents a strap of leatherof proper length,

which ,When moistened and subsequently rolled or bent, is formed intothe shape of an annular washer, B. (Shown in Fig. l.) The ends ofthestrap, when formed, may be caused to overlap, as in Fig. 2, and are thenriveted, or otherwise bound together in suitable manner. By increasingthe length of thev strap A, a thick` washer may be produced from thesame single and joined at the ends, substantially as described.

2. An annular washer constructed of a single piece, in one` or more`thicknesses of leather, by bending or rolling a strap of the requisitelength, substantially as specified.
